Botanists Identify 33 Global ‘Dark Spots’ with Thousands of Unknown Plants

A new study from Kew’s Royal Botanic Gardens has identified 33 “dark spots” worldwide, where an estimated 100,000 plant species remain undiscovered, many at risk of extinction, The Guardian reported yesterday.

Researchers emphasize the urgency of exploring these areas, which span regions from Madagascar to Bolivia, to accelerate plant identification and conservation efforts.

Prof. Alexandre Antonelli, the study’s senior author, warns that many species may vanish before being documented. The research highlights regions in Asia, Africa, and South America, urging scientists to focus on these biodiversity hotspots.

Dr. Samuel Pironon, a lead author, stresses the importance of knowing what species exist to effectively preserve biodiversity. The study encourages public engagement through citizen science, allowing individuals to contribute by photographing plants and sharing them on platforms like iNaturalist. As governments prepare for the Cop16 biodiversity summit in Colombia, the findings underscore the critical need for collaborative conservation efforts.
